Runtime.getRuntime.exec()

Posted: Jun 27, 2002 5:43 AM

Hi,

I have a question about Runtime.getRuntime().exec(). Please help me.

I want to pass in a command. The command is "cmd.exe /c C:\\executables\\blastall -p blastn -d ecoli -i test.txt";

(C:\executables\blastall is an executable code, -p to pass the program, -d to pass the database, -i to pass the input file)

But it always has error. The DOS window can appear. But it says "Abrupt = 0"

The code is below. Thnaks.

public void test()
{

String cmdLine = "cmd.exe /c C:\\executables\\blastall -p blastn -d ecoli -i test.txt";

String line = "";

try

{

java.lang.Process djProc = Runtime.getRuntime().exec(cmdLine);

djProc.waitFor();

BufferedReader input = new BufferedReader(new InputStreamReader(djProc.getInputStream()));

while ((line = input.readLine()) != null) {

System.out.println(line);

}

System.out.println("in Here");

}

catch (Exception e)

{

System.out.println(e.toString());

}
}

Try to give this as argument :

String[] cmdLine 
  = new String[] {
                   "cmd.exe",
                   "/c",
                   "C:\\executables\\blastall",
                   "-p",
                   "blastn",
                   "-d",
                   "ecoli",
                   "-i",
                   "test.txt"
                   };
